At least nine school districts in the Concord area have either already adopted these restrictive policies or added warrant articles to their annual meetings that would do so. Senate Democrats said the program would exacerbate inequalities between students and force certain school districts to close schools as students enrolled elsewhere. Twenty-five states currently mandate open enrollment, according to a report from the National Conference of State Legislatures. Already this month, residents in Kearsarge and Pembroke established open enrollment policies that would prevent any students from enrolling elsewhere at their home districts’ expense. Open enrollment is one lever Republican lawmakers have focused on in their efforts to expand educational choice in the state.
